Definitions

  • the present invention relates to an ink jet recording medium, particularly an ink jet recording medium with a fabric substrate which enables formation of a high quality image by an ink jet system, and a record.
  • JP-A-6 255 235 discloses a recording medium having a porous surface layer containing silica and boehmite on a base material composed of paper.
  • a porous silica layer is formed between the base material and the porous layer composed of psuedo-boehmite and silica.
  • JP-A-4 270 679 discloses an ink jet printable sheet made up of a fibrous material surface and an ink jet printable composition comprising of an aqueous insoluble synthetic polymer or a resin composition containing (in)organic particles.
  • JP-A-06 184 954 discloses a cloth, made of natural or synthetic fibers, to whose surface boehmite has been attached.
  • the present invention provides an ink jet recording medium comprising a substrate made of a fiber material coated on one side with porous particles having a particle size of from 0.1 to 30 ⁇ m, and a surface layer made of boehmite as the main component, formed on the other side of the substrate.
  • the fiber material for the substrate is not particularly limited, a cloth, knit or nonwoven fabric made of a synthetic or natural fiber may be used.
  • the material may, for example, be cotton, silk, hemp, wool, polyester, acrylic resin, polyamide, rayon, acetate or polyimide.
  • polyester is preferred, since the dimensional stability is good against the temperature or humidity.
  • a cloth woven with a multifilament yarn consisting of a bundle of straight and parallel fine fibers is smooth, but has small absorptivity.
  • a cloth woven with a processed yarn prepared by applying crimping or loop-processing to the multifilament yarn is preferred, since the fiber alignment is disordered to form fine spaces among fibers, whereby ink absorptivity is improved.
  • a cloth or knit made of a cationic dyeable polyester which is a polyester having an acidic substituent introduced, has good adsorptivity of boehmite, whereby boehmite can be uniformly coated around the fibers. Accordingly, it is thereby possible to obtain a clear image without bleeding, as compared with usual polyester.
  • the fiber diameter, the fabric strength, the woven density, etc. may suitably be selected depending upon the particular use such as use for a tapestry or a flag.
  • the porous particles have effects of supplementing ink absorptivity during recording to a fiber material having low ink absorptivity by the fibers themselves, such as synthetic fibers. Further, they are effective to prevent ink from passing through the substrate at the time of recording, for a coarse fiber material.
  • the porous particles are required to be particles having a particle size of from 0.1 to 30 ⁇ m. If the particle size is less than 0.1 ⁇ m, the absorptivity tends to be inadequate, such being undesirable. If the particle size exceeds 30 ⁇ m, uniform coating tends to be difficult.
  • the porous particles preferably has an oil absorption of at least 0.1 cm 3 /g, more preferably from 0.2 to 2.0 cm 3 /g.
  • the material for the porous particles may be an inorganic or organic material.
  • the inorganic material silica, clay, alumina, calcium carbonate or titanium oxide may be mentioned.
  • the organic material cellulose may be mentioned.
  • Such porous particles are preferably in a state bound by a binder.
  • the binder polyvinyl alcohol, an ethylene-vinyl acetate copolymer, an acrylic resin or a urethane resin is, for example, preferred.
  • the proportions of the porous particles and the binder are preferably such that the binder is from 5 to 300 parts by weight (dry solid content) per 100 parts by weight of the porous particles.
  • the binder is polyvinyl alcohol
  • the polyvinyl alcohol is from 5 to 50 parts by weight per 100 parts by weight of the silica.
  • the binder is an acrylic resin
  • the acrylic resin is from 50 to 200 parts by weight per 100 parts by weight of the silica.
  • the porous particles are present on one side of the fiber material.
  • To coat the porous particles to the fiber material it is preferred to coat the porous particles by dispersing the porous particles together with the binder in a suitable solvent. Coating is required to be carried out at a high solid content concentration and at a high viscosity. Accordingly, it is preferred to employ a coating method by means of e.g. a knife coater or a dip coater.
  • the porous particles are preferably coated in an amount of from 1 to 40 g/m 2 , more preferably from 5 to 20 g/m 2 .
  • the surface layer made of boehmite as the main component has a function of receiving jetted ink and fixing the colorant or dye to develop it as an image.
  • the layer preferably contains from 50 to 95 wt% of boemite.
  • the surface layer made of boehmite as the main component is preferably in such a state that boehmite particles are bound by a binder.
  • a binder an organic substance such as starch or its modified product, polyvinyl alcohol or its modified product, styrene-butadiene rubber latex, acrylonitrile-butadiene rubber latex, carboxymethyl cellulose, hydroxylmethyl cellulose, or polyvinyl pyrrolidone may, for example, be mentioned.
  • the amount of the binder is preferably from 5 to 50 wt% of the boehmite. If the amount of the binder is less than 5 wt%, the strength of the boehmite surface layer tends to be inadequate, such being undesirable. If the amount of the binder exceeds 50 wt%, the ink absorptivity and the colorant-fixing property tend to be inadequate, such being undesirable.
  • the surface layer made of boehmite as the main component is formed on the surface not coated with the porous particles.
  • the coated amount of the boehmite surface layer is preferably within a range of from 2 to 60 g/m 2 . If the coated amount is less than 2 g/m 2 , the colorant-fixing property and the ink absorptivity tend to be inadequate, whereby clear and high color density recording can not be obtained. If the coated amount exceeds 60 g/m 2 , not only the material is consumed unnecessarily, but also the flexibility of the substrate tends to be impaired, such being undesirable. More preferably, the coated amount is from 4 to 30 g/m 2 .
  • a carboxylic acid such as malonic acid, succinic acid, adipic acid, maleic acid, oxalic acid, phthalic acid, isophthalic acid or terephthalic acid to the surface layer made of boehmite as the main component, in an amount of from 0.05 to 7.5 wt% based on the boehmite, whereby coloring caused by adsorption of e.g. a plasticizer on the boehmite layer, can be prevented.
  • a carboxylic acid such as malonic acid, succinic acid, adipic acid, maleic acid, oxalic acid, phthalic acid, isophthalic acid or terephthalic acid
  • a method may be employed wherein a coating liquid obtained by adding a binder to a boehmite sol, is coated by means of e.g. a roll coater, an air knife coater, a blade coater, a rod coater, a bar coater, a comma coater, a die coater or a gravure coater, followed by drying.
  • a coating liquid obtained by adding a binder to a boehmite sol is coated by means of e.g. a roll coater, an air knife coater, a blade coater, a rod coater, a bar coater, a comma coater, a die coater or a gravure coater, followed by drying.
  • the effects of adsorbing the dye can be increased, so that an image having a higher density and higher clarity can be obtained. Further, it is possible to improve the water resistance of the dye.
  • a polyethylene imine, a polyamide resin, a polyamine resin, a reaction product of a low molecular weight polyfunctional amine with a compound polyfunctional to amino groups, such as epihalohydrin, an acrylamine copolymer resin (such as a quaternary ammonium salt polymer), a polyamide epichlorohydrin resin, or a modified product thereof, may be employed.
  • a cationic resin having a high molecular weight such as a polyethylene imine with a molecular weight of at least 10,000.
  • crosslinking it is possible to employ a method of adding a thermosetting resin such as a urea resin, a melamine resin, an amide resin or an epoxy resin, to a cationic resin such as polyamine or polyethylene imine, or a method of curing by an addition of an electron beam or ultraviolet ray curable resin such as a polyester acrylate, a polyether acrylate, an epoxy acrylate or a urethane acrylate.
  • the cationic resin layer is preferably formed by coating the porous particles on the fiber material, and then impregnating or coating a liquid having the cationic resin dissolved or dispersed in a suitable solvent. Otherwise, the cationic resin may be incorporated to the porous particles beforehand.
  • the weather resistance and scratch-resistance of the record can be remarkably improved. Even in a case where recording is made only on one side, the weather resistance of the record can further be improved by coating a similar resin also on the side opposite to the recorded side. In a case where the record is observed only from one side, the coating on the other side may be opaque.
  • the coating resin is preferably hydrophobic.
  • Coating the surface of the record is carried out after recording.
  • the other side may be coated after recording, but it is preferred that the other side is coated prior to recording, whereby the coating treatment can be carried out conveniently.
  • a silica coating liquid was prepared by mixing a porous silica powder having an average particle size of 2 ⁇ m (Carplex FPX-3, tradename, manufactured by Shionogi & Co., Ltd.), a 45 wt% solution of a hydrophilic acrylic resin and water in a weight ratio of 25:100:125.
  • This silica coating liquid was coated on one side of a polyester cloth (weight: 150 g/m 2 , warp: 150 d, weft: 200d) by means of a knife coater and dried. The coated amount was 15 g/m 2 as dry base.
  • a boehmite coating liquid having a total solid content concentration of 10 wt% was prepared by mixing a boehmite sol (solid content concentration: 18 wt%, dispersed particle size of boehmite: 150 nm), polyvinyl alcohol (saponification degree: 96.5%, 4% viscosity: 65 cps, MA26, tradename, manufactured by Shin-Etsu Chemical Co., Ltd.) and succinic acid in a weight ratio of 100:6:2.
  • This boehmite coating liquid was coated on the other side of the silica-coated surface of the polyester cloth by means of a bar coater and dried at 140°C. The coated amount was 15 g/m 2 as dried.
  • silica was coated on a polyester cloth, and then a 5 wt% aqueous solution of a cationic resin (water-soluble polyamide resin, Sumitex Resin AR-5, tradename, manufactured by Sumitomo Chemical Co., Ltd.) was coated on the other side of the silica-coated surface by means of a bar coater. After drying, boehmite was coated on the cationic-resin-coated surface in the same manner as in Example 1.
  • a cationic resin water-soluble polyamide resin, Sumitex Resin AR-5, tradename, manufactured by Sumitomo Chemical Co., Ltd.
  • silica was coated on a polyester cloth, and then a 5 wt% aqueous solution of a cationic resin (water-soluble polyamide resin, Sumitex Resin AR-5, tradename, manufactured by Sumitomo Chemical Co., Ltd.) was coated on the other side of the silica-coated surface by means of a bar coater.
  • a cationic resin water-soluble polyamide resin, Sumitex Resin AR-5, tradename, manufactured by Sumitomo Chemical Co., Ltd.
  • Example 1 On the recording media of Examples 1 to 3, printing was carried out with four colors of magenta, cyan, yellow and black, by means of an ink jet printer.
  • a cloth treated up to the silica coating in Example 1 was used. The image quality was visually evaluated, and the results are shown in Table 1.
  • Table 1 o ⁇ indicates that the image quality is excellent, ⁇ indicates that the image quality is good, ⁇ indicates that the image quality is fair, and x indicates that the image quality is poor.
  • Comparative Example presented a whitish image quality with color fading. Then, for evaluation of water resistance, the recording medium after printing was immersed in water for 4 hours, whereby bleeding of magenta was visually observed and relatively evaluated in a similar manner. Further, the color density was measured before and after the immersion, to obtain the ratio of the color density after immersion to the color density before immersion.
  • the ink jet recording medium of the present invention With the ink jet recording medium of the present invention, a clear color image can easily be prepared by an ink jet printer, and an output of an image on a large area is also easy. Further, the durability of the image is high.
  • the record by this recording medium can be used for an advertising sign, a flag or a tapestry. When a coating layer is formed after printing, a record having particularly high durability can be obtained, which is sufficiently durable for use outdoors for a long period of time.
